Black ghost knife fish?

[Dale]

Hi SWM,
The black ghost will be fine for a couple of months with those other guys as long as you give it (the ghost) a tube to hide in. They are the smaller of the knifes (unlike the 3' clownknifes) but will still try to eat anthing that fits in their mouth. Like elephantnose fish they use an electrical impulse organ to seek out food in the wild.
